Abstract
Tungsten trioxide (WO3) was prepared from the precursor sodium tungstate (Na2WO4·2H2O) in the presence HCl by cost-effective and eco-friendly facile hydrothermal method at different operating temperature 120, 150, 180 and 210 °C during autoclave reaction. Different properties like morphology, optical properties, structure tailoring and degradation rate of prepared samples were studied by characterization like SEM, EDX, XRD and photocatalysis respectively. The photocatalytic activity test was examined to degrade RhB dye under visible light irradiation. Experimental results revealed the higher photocatalytic performance at 180 °C. The better photocatalytic activity obtained due to extended region of visible light, lower particle size, better morphology and lower recombination rate.
